First contact made after discovering the existence of the microbrains of Velara III, who had been attempting contact themselves. They request to be left alone for three centuries and would consider re-opening communications with the Federation in 2664. (TNG: "Home Soil")

In the game Star Trek: Armada, a Borg sphere arrives from 2376 to destroy the Enterprise-D and kill Picard, to prevent a Borg defeat in that time period. Seconds later, the USS Premonition arrives to destroy the sphere. Succeeding, it immediately returns to 2376 to prevent any further contamination to the timeline. Captain Picard remembers this encounter, and no further reference is heard about this encounter until 2376 where he states he has seen the ship before.
